Pd-induced quenching of the UV emission from Gd ions in phosphate glass.

This paper reports on the influence of Pd ions on the ultraviolet emission from Gd, investigated in barium phosphate glass as model matrix. The glasses were prepared by the melting technique and characterized by X-ray diffraction (XRD), Fourier transform-infrared (FT-IR) spectroscopy, optical absorption, and photoluminescence (PL) spectroscopy including decay kinetics assessment. The XRD data confirmed the amorphous nature of the glasses, whereas FT-IR spectra indicated the basic structural features of PO tetrahedra.
